The Iliad, Book 12

Flash forward-- far in the future, well after the fall of Troy and the Greeks return home, Zeus and Poseidon will destroy the Greeks' wall and ditch with a flood, wiping away all trace of the siege.  For now, it is the site of battle.  Trojans dismount to overwhelm the stronghold on foot, except one company who remain on horses and are destroyed.  Both sides are unflinching until Sarpedon breaches the wall's defenses, and Hektor breaches the wall itself.  Trojans on their way to the ships, ready to finish the job.
